If the target is an ARM architecture then this switch can be used to
select which register name set is used during disassembler. Specifying
-@samp{--disassembler-options=reg-name-std} (the default) will select the
-register names as used in ARM's instruction set documentation, but with
-register 13 called 'sp', register 14 called 'lr' and register 15 called
-'pc'. Specifying @samp{--disassembler-options=reg-names-apcs} will
-select the name set used by the ARM Procedure Call Standard, whilst
-specifying @samp{--disassembler-options=reg-names-raw} will just use
-@samp{r} followed by the register number.
+@samp{-M reg-name-std} (the default) will select the register names as
+used in ARM's instruction set documentation, but with register 13 called
+'sp', register 14 called 'lr' and register 15 called 'pc'. Specifying
+@samp{-M reg-names-apcs} will select the name set used by the ARM
+Procedure Call Standard, whilst specifying @samp{-M reg-names-raw} will
+just use @samp{r} followed by the register number.
+
+There are also two variants on the APCS register naming scheme enabled
+by @samp{-M reg-names-atpcs} and @samp{-M reg-names-special-atpcs} which
+use the ARM/Thumb Procedure Call Standard naming conventions. (Eiuther
+with the normal register name sor the special register names).
+
+This option can also be used for ARM architectures to force the
+disassembler to interpret all instructions as THUMB instructions by
+using the switch @samp{--disassembler-options=force-thumb}. This can be
+useful when attempting to disassemble thumb code produced by other
+compilers.

@var{val} should be a hexadecimal language code. The low eight bits are
the language, and the high eight bits are the sublanguage.
+@item --use-temp-file
+Use a temporary file to instead of using popen to read the output of
+the preprocessor. Use this option if the popen implementation is buggy
+on the host (eg., certain non-English language versions of Windows 95 and
+Windows 98 are known to have buggy popen where the output will instead
+go the console).
+
+@item --no-use-temp-file
+Use popen, not a temporary file, to read the output of the preprocessor.
+This is the default behaviour.
